The intention was originally with this change was that it would find all troops that use only those colours selected (e.g. only blue brings up ALL blue), so selecting one colour would function the same between the Any and All options. This results in you not being able to find any troops with only x1 mana colour (or color!)
We have fixed this. In 3.5 selecting “All” with only one mana color selected will show only mono-coloured troops (for example, selecting blue only and “All” brings up dwarven gate, justice etc)
Summary
- Selecting 2 gem mana colors and ANY COLOR (e.g. red/yellow selected) gives results for troops with red OR yellow mana colors
- Selecting 2 gem mana colors and ALL COLORS will only show troops with both mana colors that you selected (i.e only troops that use both red/yellow mana).
